A successful reflight of SpaceX's Super Heavy booster would be an important milestone for its Starship program.

Board game designer and entrepreneur Jamey Stegmaier has published hit games like Scythe and Wingspan—the latter a personal favorite of mine, with a delightfully gentle theme about birds—but this week found him in a gloomy mood.

"Last night I tried to work on a new game I'm brainstorming," he wrote in a blog post yesterday, "but it’s really hard to create something for the future when that future looks so grim. I mostly just found myself staring blankly at the enormity of the newly announced 54 percent tariff on goods manufactured in China and imported to the US."

Most US board games are made in China, though Germany (the home of modern hobby board gaming) also has manufacturing facilities. While printed content, such as card games, can be manufactured in the US, it's far harder to find anyone who can make intricate board pieces like bespoke wooden bits and custom dice. And if you can, the price is often astronomical. "I recall getting quoted a cost of $10 for just a standard empty box from a company in the US that specializes in making boxes," Stegmaier noted—though a complete game can be produced and boxed in China for that same amount.

Plant cells are surrounded by an intricately structured protective coat called the cell wall. It’s built of cellulose microfibrils intertwined with polysaccharides like hemicellulose or pectin. We have known what plant cells look like without their walls, and we know what they look like when the walls are fully assembled, but we’ve never seen the wall-building process in action. “We knew the starting point and the finishing point, but had no idea what happens in between,” says Eric Lam, a plant biologist at Rutgers University. He’s a co-author of the study that caught wall-building plant cells in action for the first time. And once we saw how the cell wall building worked, it looked nothing like how we drew that in biology handbooks.

Camera-shy builders

Plant cells without walls, known as protoplasts, are very fragile, and it has been difficult to keep them alive under a microscope for the several hours needed for them to build walls. Plant cells are also very light-sensitive, and most microscopy techniques require pointing a strong light source at them to get good imagery.

Then there was the issue of tracking their progress. “Cellulose is not fluorescent, so you can’t see it with traditional microscopy,” says Shishir Chundawat, a biologist at Rutgers. “That was one of the biggest issues in the past.” The only way you can see it is if you attach a fluorescent marker to it. Unfortunately, the markers typically used to label cellulose were either bound to other compounds or were toxic to the plant cells. Given their fragility and light sensitivity, the cells simply couldn’t survive very long with toxic markers as well.

The white-necked jacobin (Florisuga mellivora) is a jewel-toned hummingbird found in the neotropical lowlands of South America and the Caribbean. It shimmers blue and green in the sunlight as it flits from flower to flower, a tiny spectacle of the rainforest.

Jay Falk, a National Science Foundation postdoctoral fellow at the University of Colorado, Boulder, and the Smithsonian Tropical Research Institute (STRI) in Panama, expected to find something like that when he sought this species out in Panama. What he didn’t expect was a caterpillar in the nest of one of these birds. At least it looked like a caterpillar—it was actually a hatchling with some highly unusual camouflage.

The chick was covered in long, fine feathers similar to the urticating hairs that some caterpillars are covered in. These often toxic barbed hairs deter predators, who can suffer anything from inflammation to nausea and even death if they attack. Falk realized he was witnessing mimicry only seen in one other bird species and never before in hummingbirds. It seemed that the nestlings of this species had evolved a defense: convincing predators they were poisonous.

In an unprecedented move, Nintendo has pushed preorders for its highly anticipated Switch 2 to an unknown date. Why? Trump’s tariffs.

Will this Chevrolet Silverado EV be the biggest electric vehicle we test this year? Almost certainly. Fractionally narrower and less tall than a Hummer EV pickup at more than 18 feet (just under 6 m) long and with a curb weight of 8,532 lbs (3,870 kg), the Silverado EV is what happens when Chevy's electric vehicle engineers get tasked with making their rivals over at Ford feel like they didn't try hard enough with the electric F-150.

Now that production has been ongoing for a while, Chevy is filling out the lower trim levels. For commercial customers, there's a Work Truck, but for normies, the entry point is now the LT trim, at a tax credit-friendly—if still wallet-munching—$75,195 (for as long as the tax credit still lasts and until the effect of pointless and damaging trade tariffs make themselves known, of course).

The 645 hp (481 kW), 756 lb-ft (1,037 Nm) Silverado EV LT comes with the smaller of the two battery packs offered to non-commercial customers. That adjective is doing a lot of work there; a useable 170 kWh is indeed smaller than the 200 kWh you can find in the more expensive RST Max Range, but it's also more than double the capacity of something like a Hyundai Ioniq 5. The range estimate is a commensurate 408 miles (657 km), or "just" 390 miles (628 km) if, as in our test pickup, the premium package has been fitted.

Nintendo Switch 2 preorders, which were due to begin on April 9, are being delayed indefinitely amid the financial uncertainty surrounding Donald Trump's recent announcement of massive tariffs on most US trading partners.

"Pre-orders for Nintendo Switch 2 in the U.S. will not start April 9, 2025 in order to assess the potential impact of tariffs and evolving market conditions,” Nintendo said in a statement cited by Polygon. "Nintendo will update timing at a later date. The launch date of June 5, 2025 is unchanged."

Nintendo announced launch details for the Switch 2 on Wednesday morning, just hours before Trump's afternoon "Liberation Day" press conference announcing the biggest increase in import duties in modern US history. Those taxes on practically all goods imported into the United States are set to officially go into effect on April 9, the same day Nintendo had planned to roll out Switch 2 preorders for qualified customers.

Outside of several mentions in the Rocket Report newsletter dating back to 2018, Ars Technica has not devoted too much attention to covering a novel California space company named SpinLaunch.

That's because the premise is so outlandish as to almost not feel real. The company aims to build a kinetic launch system that spins a rocket around at speeds up to 4,700 mph (7,500 km/h) before sending it upward toward space. Then, at an altitude of 40 miles (60 km) or so, the rocket would ignite its engines to achieve orbital velocity. Essentially, SpinLaunch wants to yeet things into space.

But the company was no joke. After being founded in 2014, it raised more than $150 million over the next decade. It built a prototype accelerator in New Mexico and performed a series of flight tests. The flights reached altitudes of "tens of thousands" of feet, according to the company, and were often accompanied by slickly produced videos.

For two decades, farmer John Burk has been working to improve the soil on his farm in Michigan, taking a few extra steps to make it more resilient and productive. His efforts have paid off.

“When we have the dry, hot summers or lack of rainfall, our crops can sustain the dry spells better. We don’t have huge yield decreases,” Burk said. “And when it rains and we have the freak storms, like it seems to do so much now, we don’t have the ponding and all the runoff.”

An added bonus: He needs less fertilizer, a major operating expense.

If you love the backcountry, this tiny, tough, and relatively affordable satellite communicator can give you peace of mind.

Andrew Cunningham and Lee Hutchinson have spent decades of their lives with Robert Jordan and Brandon Sanderson's Wheel of Time books, and they previously brought that knowledge to bear as they recapped each first season episode and second season episode of Amazon's WoT TV series. Now we're back in the saddle for season 3—along with insights, jokes, and the occasional wild theory.

These recaps won't cover every element of every episode, but they will contain major spoilers for the show and the book series. We'll do our best to not spoil major future events from the books, but there's always the danger that something might slip out. If you want to stay completely unspoiled and haven't read the books, these recaps aren't for you.

New episodes of The Wheel of Time season 3 will be posted for Amazon Prime subscribers every Thursday. This write-up covers episode six, "The Shadow in the Night," which was released on April 3.
